- These functions write the characters of the (null-terminated) wchar_t - character string wstr on the given window. It is similar to construct- - ing a cchar_t for each wchar_t in the string, then calling wadd_wch for - the resulting cchar_t. + waddwstr writes the characters of the (wide-null-terminated) wide- + character string wstr to the window win. Its process is similar to + constructing a cchar_t for each wchar_t in wstr, then calling + wadd_wch(3x) with the resulting cchar_t. - The mv functions perform cursor movement once, before writing any char- - acters. Thereafter, the cursor is advanced as a side-effect of writing - to the window. + o Spacing and non-spacing characters in the string are processed one + at a time, and - The four functions with n as the last argument write at most n wchar_t - characters, or until a terminating null is reached. If n is -1, then - the entire string will be added. + o control characters are processed as in wadd_wch(3x). + + waddnwstr writes at most n wide characters, or until a terminating wide + null character occurs in wstr.
